Flanged End Swing Check Valve

Technical Specifications

The swing check valve is a kind of check valve that is commonly used in water pumping systems. It got its name from the fact that it is composed of a body and a disc that swings or pivots through a hinge pin. The disc serves to prevent the reverse flow or to allow forward flow. Simply put, this valve allows flow in one direction (forward flow) and automatically prevents back flow (reverse flow). The main function of a swing check valve is to prevent back flow and protect any item or equipment that might be destroyed during a reverse flow. It also prevents hydraulic pressure surges and flooding.

This type of valve is quite popular because it is easily accessible and has low maintenance costs when in use. Aside from that, it is self-automated; it does not require assistance to operate. Unlike other valves, it will still work even if there is no electricity, or there is no human to operate the valve.

Functions of swing check valves

This kind of valve usually operates for systems that make use of a gate valve because of the low pressure. The disc is suspended from the body through the hinge pin.
At the point of pivot, the water will flow back into the valve, even before the disc is shut off. In order to completely shut down, the disc must go through a complete 90 degree angle.
